DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

Referring to FIG. 1, FIG. 1 is a flow chart of a method for inputting multiple events in accordance with a first embodiment of the present invention. The present embodiment provides a method for inputting multiple events including the following steps.

Step S101, receiving touch signals produced by a touch screen corresponding to a touch action of a user's finger.

When the user's finger touch the touch screen, the touch screen could sense the users' touch action and produce corresponding touch signals. The touch screen can be a resistance type touch screen, or a capacitive type touch screen. Generally, the touch screen includes a number of pixels arranged in an array and each pixel is a separate detecting unit. Each detecting unit positions the user's touch action by detecting the resistance variation or capacitance variation caused by the touch action of the user's finger. The touch screen may use an absolute positioning method, that is, each pixel has a fixed coordinates (x,y). When the user's finger touches the touch screen, detecting units corresponding to each pixel is scanned to obtain a touch signal set A[(x₁,y₁), (x₂,y₂), . . . (x_(n),y_(n))] described by coordinates and detected signal intensity, and then the touch action of the user is determined according to the touch signals.

Step S102, ascertaining a touch direction of the user's finger to the touch screen according to the touch signals.

Currently, the touch action of the user's finger usually includes the following types: single click, multiple clicks, swipe gestures or multi-touch. For the touch actions of single click, multiple clicks, swiping or multi-touch, the touch screen is capable of recognizing the type of touch action according to the intensity distribution, time continuity or space continuity of touch signals. In the present embodiment, a touch direction of the touch action is further determined. The methods for determining the touch direction includes a method described in the following context based on the recognition of the finger's muscle portion and non-muscle portion, and can also include other methods that are capable of achieving recognition of different touch directions.

Step S103, triggering different events corresponding to different touch directions of the user's finger.

In the present embodiment, different touch directions are corresponding to different events. That is, when the user touches the touch screen at different directions, different events are triggered. In the step S102 of the present embodiment, the touch direction of the user's finger to the touch screen is divided into a first direction of a second direction. In the present embodiment, if the touch direction is the first direction, a launching event is triggered, and an application corresponding to an icon is launched. If the touch direction is the second direction, a selecting event is triggered, and an icon corresponding to the touch point is selected. The events triggered in the above description is the default configuration, however the user can also custom the events triggered by the different touch directions according to their own operation habits.

The above description mainly describes the process of triggering single click. Furthermore, the touch directions of multiple clicks, swipe gestures and multi-touch can also be divided to trigger different events.

Differing from the existing art, in the present embodiment, the touch screen produces different touch signals when the user's finger touches the touch screen in different manners. Thus, the touch direction of the user's finger on the touch screen can be determined according to the touch signals, and different events can be triggered according to the different touch directions. In detail, different touch signals are recognized using the pressure signals or touch area signals to determine the touch direction of the user's finger and trigger different events.

Referring to FIG. 2, FIG. 2 is a flow chart of a method for inputting multiple events in accordance with a second embodiment of the present invention. The present embodiment provides a method for inputting multiple events including the following steps.

Step S201, receiving touch signals produced by a touch screen corresponding to a touch action of a user's finger.

This step is similar to the step S101 described in the first embodiment.

Step S202, determining whether a muscle portion and a non-muscle portion of the finger both touch the touch screen or only the muscle portion of the finger touches the touch screen according to the touch signals.

In the present embodiment, resistance variation or capacitance variation caused by the muscle portion and the non-muscle portion of the finger are different when the finger touches the touch screen. Thus, touch signals produced by the touch screen corresponding to the two portions are also different, and the touch direction can be distinguished by judging is only the muscle portion touches the touch screen, is only the non-muscle portion touches the touch screen, or both the muscle portion and the non-muscle portion touch the touch screen. For example, the muscle portion is the fingernail, and the muscle portion is the finger body. Specifically, if the touch signals show that both the muscle portion and the non-muscle portion of the finger touch the touch screen, then the touch direction is the first direction; and if the touch signals show that only the muscle portion of the finger touches the touch screen, then the touch direction is the second direction. In other embodiments, the touch direction is defined as a third direction if the touch signals show that only the non-muscle portion of the finger touches the touch screen. If touch signals produced by different touch actions can be recognized, then a number of touch directions can be recognized correspondingly.

As shown in FIG. 3, whether a muscle portion and a non-muscle portion of the finger both touch the touch screen or only the muscle portion of the finger touches the touch screen is determined according to intensity variation of the touch signals, or according to the shape or size of a touching area of the touch screen. Specifically, the intensity variation of produced touch signals can be presented by a pattern of single square wave a₁ when only the muscle portion of the user's finger touches the touch screen. The intensity variation of produced touch signals can be presented by a pattern including two continuous square waves b₁ and b₂ when both the muscle portion and the non-muscle portion (fingernail) touch the touch screen. In addition, the touch area is an elliptical area A₁ of a predetermined size when only the muscle portion of the user's finger touches the touch screen, and the touch area includes an arc-shaped area B₁ and an elliptical area B₂ adjacent to the arc-shaped area when both the muscle portion and the non-muscle portion touch the touch screen. Besides, the size ratio of the arc-shaped area and the elliptical area is in a predetermined range.

Step S203, determining the touch direction of the user's finger according to whether a muscle portion and a non-muscle portion of the finger both touch the touch screen or only the muscle portion of the finger touches the touch screen.

If both the muscle portion and the non-muscle portion touch the touch screen, then the touch direction of the finger is the first direction, and if only the non-muscle portion touches the touch screen, then the touch direction of the finger is the second direction.

Step S204, triggering different events according to different touch directions of the user's finger.

According to the touch direction, if the touch direction is the first direction, then a first event is triggered; and if the touch direction is the second direction then a second event different with the first event is triggered. The first event, for example, presents to launch something or move something, and the second event present to select or end select. In addition, the actions corresponding to the first event and the second event can be customized. When the user doesn't change the configuration, the first event presents to launch an icon at a touch position corresponding to the first event in the default mode, and the second event presents to select an icon at a touch position corresponding to the second event. In detail, referring to FIG. 4, taking an operation to a music menu as an example, a music corresponding to a menu item is played when the touch direction of the user's finger is the first direction. The menu item is selected when the touch direction of the user's finger is the second direction, and an editing menu of a music corresponding to the menu item is entered.

Differing from the existing art, the present embodiment can determine the touch direction of the user's finger is the first direction or the second direction by determining whether the touch area of the finger is elliptical and arc-shaped, or only elliptical, and thus different events can be triggered.

Referring to FIG. 5, FIG. 5 is a schematic view of a terminal for inputting multiple events in accordance with a fourth embodiment of the present invention. The present invention provides a terminal 500 including a touch screen 501 and a processor 502.

The touch screen is configured for producing touch signal corresponding to touch actions of the user's finger.

In the present embodiment, the touch screen 501 further includes a number pixels 5011 arranged in a matrix, and each pixel 5011 includes a detecting unit 5012. When the user's finger touches the touch screen 501, the detecting units 5012 in the pixels 5011 within a touch area can detect the touch signals and transmit the touch signals to the processor 502.

The processor 502 is configured for ascertaining a touch direction of the user's finger to the touch screen according to the touch signals; and triggering different events corresponding to different touch directions of the user's finger.

The coordinates of the pixels 5011 in the touch screen are recorded in the processor 502. When the detecting units 5012 transmit the touch signals to the processor 502, the processor 502 records the signal intensity and coordinates of corresponding detecting units. Each touch action has a corresponding touch signal. For multiple clicks, the continuous clicks in a predetermined time period are regarded as multiple clicks, for example, when the time difference between two clicks is within 3 s then the two clicks are regarded as a multi-click, and when the time difference exceeds 3 s then the two clicks are regarded as two separate single clicks. For a multi-click, the touch signals further includes the times of clicks. For a swipe gesture, the touch signals further includes the displacement information.

After receiving the touch signals, the processor 502 recognize the touch signals to determine the touch direction of the user's finger on the touch screen, and then triggers different events according to different touch directions. The touch directions of the user's finger includes two types, the first direction if both the muscle portion and the non-muscle portion of the user's finger touch the touch screen 501, and the second direction if only the muscle portion of the users finger touches the touch screen 501. If the touch direction is the first direction, the processor 502 triggers the first event, and if the touch direction is the second direction, the processor 502 triggers the second event different with the first event.

In the terminal 500, the first event is configured for launching an icon at a touch point corresponding to the first event; and the second event is configured for selecting an icon at a touch point corresponding to the second event, according to default mode. The user can also customize the function corresponding to the different events.

The work process of the terminal 500 includes the following steps. Firstly, the touch screen 501 produces touch signals corresponding to a touch action. Then the processor 502 receives the touch signals produced by the touch screen 501, determines the touch direction, and further triggers different events. This process is similar to the flow described in the method for inputting multiple events of the second embodiment.

Differing from the existing art, the touch screen of the present embodiment can detect the touch action of the user and transmit the touch signals to the processor. The processor processes the touch signals to determine the touch direction, and further triggers different events.

The above description is only embodiment of the present invention, and is not used to limit the scope of the present invention.
